The girls were in the studio to record their Japanese debut song "No No No" when they got to talking about their auditions. Eunji shared that she sang a song by Big Mama and completely captured the judges' hearts, adding that she was one of the few idols lucky enough to debut with no training.

Eunji had her vocals down, but she also made sure to practice her dancing to Taeyang's "I Need a Girl" with a few of her hometown friends to make the complete package.
